T0 all lw71 om it may concern:

Be it known that l, GRANT B. Smrnnr, resident of Pittsburgh, in the county o Allegheny and State of Pennsylvania, have invented a new and useful Improvement in food-Treating Cylinders, of which the fol lowing is a specification. f

This invention relates to vertical .treating cylinders for use in Wood preserving in stallations.

The object of the invention is to provide a vertical treating cylinder in which the operations of charging and discharging the same may he carried on at a level with the top of the cylinder, and one which eilects its object hy timber supporting means airanged to he lowered gradually in the cylinder during charging and discharging, of the saine, so that the upper portion of the pile of timliers thereon may he'niaintained substantially level with the top of the treating cylinder. l

A further object of the invention is to provide a vertical treating cylinder possessing the foregoing qualities and which is capable of accommodating timbers ot relatively large size, as for instance railway cross ties.

ln the accompanying drawings, Figure l is a vertical sectional View of the treating1 cylinder; and Fig. 2 is a 'view showing the vertical treating cylinder in elevation and also illustrating one arrangement of means for use in conjunction with said vertical cylinder for charging or discharging the saine.

The treating cylinder l is vertically disposed and as shown in Fig. l is supported in position by means of ,shores 2. It may, however, he designed to rest directly on the platform or on the ground, or may, it desired, be sunk in the ground so as to bring its top substantially on a level with the surface. The top 3 of the cylinder' is formed to be entirely removable and the opening at the top or' the .cylinder is of a diameter substantially equal to that of the cylinder in order to permit of the introduction of large timbers for treatment. ln the cylinder is a vertically movable platform 4, which as illustrated, is movable vertically by means of the power plunger 5 of a suitable hydraulic or other power cylinder 6.v The platform is provided on its under side with guide wheels 7 cooperating with guide rails 8 in order to relieve the plunger of strains with the top of the treating cylinder 'untilv said cylinder is completely charged with timber. The top is 'then placed in position and a preserving fluid introduced by any suitable means and the charge of timber treated for any necessary length of time," after .which 'the top is removed and the ties: are discharged from the cylinder, the level;

ofthe top of the pile of ties or timbers in this operation, as in the operation of charging, being at all times even with the lei/el oi the top of the cylinder. Any suitable ar-l rangement or' mechanism may be used for raisinsT and lowering platform 4,, the power plunger illustrated being merely the pre ferred forni of actua-ting means. The plat form 4 may he raised and lowered hy means of cables secured to the platform and passing over the guide sheaves at the top of' the cylinder and over a suitably actuated Winding drum, hy which means an `eidect similar to that produced hy the power plunger .is obviously obtained.

When the cylinder is erected in a position elevated above the surface of the ground, as is preferred, means 'for raising timbers to the top of the cylinder and lowering them therefrom. must necessarily loe provided. yin Fig. 2 one foi-in oi means adapted for performing this Work is shown diagrammatically in conjunction with the treating cylinder. This charging' and discharging means is shown as a piling machine or 'elevator 9, running upon a track l0 adjacent tothe cylinder, and an endless chain conveyer ll. adapted to convey timbers from any suitable source of supply to point adjacent the treating cylinder.

The piling machine 9, as illustrated, comprises an endless chain ik?. running over a guide sheave 13 at the upper extremity of the frame of the machine, over take-up sheaves li, and around the guide sheave 15 mounted at the outer end of a. pivoted arm or boom 16. The piling machine illustrated is thus adapted to remove ties or timbers from storage piles to conveniently place them in suitable means, es for instance the conveyer ll, for transportation to the f treating cylinder, and to elevate them therefio from to the top of a cylinder.

The treating cylinder described has the great advantage that it reduces the labor necessary; in placing timber to be treated in the cylinder and removing it Itherefrom.

. When a piling machine of the general nature of the one described is used, it is merely necessary in charging or discharging the cylinder that one man may be stationed at the top of the treating cylinder and another at thepfoot of the piling machine to handle b obvious that the cylinder described is adapted for use with a great variety of means for charging and discharging the same, the

means actually shown being merely illustrative of the general mode of operation in treating -wood by means of this cylinder.

What I claim is l. A vertical wood treating cylinder hav- Y ing in its top a receiving and discharge opening, a platform in said cylinder upon which the charge is supported, and means for raising and lowering said platform so arranged that throughout theA operations of loading and unloading the top of the charge upon said platform may be maintained substantially level with the top of the 'treating cylinder.

2. A vertical wood treating cylinder having in its top a receiving and discharge opening of a diameter substantially equal to the diameter of the cylinder chamber, a platform in said cylinder upon which the charge is supported, and means for raising and lowering said platform so arranged that throughout the operations of loading and unloading the top of the charge upon tially level with the top of the treating cylinder.

8. A vertical wood'treating cylinder having in its top a receiving and discharge opening, a vertically movable charge supporting platform in said cylinder, and a power plunger for raising and lowering said platform so arranged that throughout the operations of loading and unloading the top of thecharge upon said platform may be maintained.substantially level with the top ofv the'treating cylinder.

4. A vertical wood treating cylinder having in its top a receiving and discharge opening, la vertically movable charge supporting platform in said cylinder, and mechanism arranged to be operated to lower said platform in said cylinder gradually during the operation of placing the charge thereon and similarly raise the same as the charge is removed therefrom.

i In testimony whereof, l have hereunto set my hand. y
